I'm new to TFP. I just had a replaster done using Pebblesheen, including the final acid wash; a few days after the fill the builder turned it over to me. My first test shows a CH of 80 (low!), with the other levels as follows:
FC 3.0/CC 0
Testing temp = 68F/pool = 60F. I wasn't on hand, but the builder added at least CYA (found an empty can) and left me some acid and cal hypo shock. My fill water has a CH of 130, so where did all of the CH go? With my old (plaster) finish, I was always fighting to keep CH <400 as you would expect in So AZ. If the new Pebblesheen needs & is consuming CH I'll gladly add some Ca, but otherwise I hate to add it just to have to surely drain it out later this summer. Brushing generates just a bit of 'dust' and my K/K is picking up some loose pebbles, which I think is normal. My filter has stayed right at its 'clean' backpressure since the fill. The recent 12F cold snap here either killed or defoliated most nearby trees, whose abundant debris has now been ending up in the pool. I just net it out daily and haven't let it accumulate. I have tons of CaCO3 as caliche throughout my yard, but none is white unfortunately! Thanks for any input...
